Learn How to Win the Endgame: Zugzwang
This chess endgame is a classic example of using king activity to punish an overextended defender. The key idea is that a seemingly active enemy piece can actually be vulnerable when it has no safe squares and the king can take control of the position. In classical chess, these positions often hinge on precise tempo moves, where every step restricts the opponent further. The result is a decisive material gain that converts into a winning king and pawn ending.
